IPzoom

Synopsis

zoom an ip_Image with floating point pixel offset

Input Ports

Parameters

Output Ports

Description

IPzoom scales an ip_Image with floating point offsets. This enables you to offset a zoomed image by fractional pixels.

Input Ports

&in_image

The input is a reference to an ip_Image. The ip_Image be of any type.

Parameters

MethodsRB

UIradioBox. Selects the type of interpolation to use. The choices are:

Nearest Neighbor (default)
Bilinear
Bicubic
Adaptive Support (can only be used if X Scale and Y Scale <= 0.5)

With Adaptive Support, the value of each pixel in the output ip_Image is calculated by averaging the values of a block of pixels in the input ip_Image. The size of this block is determined by the scale factor such that all the pixels in the input ip_Image affect a pixel in the output ip_Image.

X Offset
Y Offset

Float sliders. Specify the coordinate offsets of the first pixel in the zoom area. The default for both is 0. The range for both is 0 to dim - 1.

X Scale
Y Scale

Float sliders. Specify the x and y zoom factors. These must be >= 0. The default for both is 1. The range is 0.01 to 10.

Output Ports

dst

The output is a new ip_Image of the same type and bands as the input ip_Image. Currently there is a restriction where the output dimensions can only be the same as the input.

TmpField

This output is the ip_Image converted back into an AVS/Express field.

obj

This is a renderable version of the output image.
